The solid-phase lap joining of layered thin metal materials is done by using the friction stir action. The proposed method can join the interface between the layered dissimilar metal materials with the minute joining width 1 mm or less. As the dissimilar materials, aluminum material and stainless steel are used. The rotating tool for friction-stir action is pressed down onto the upper thin aluminum plate, which is layered on the thin stainless steel. The generated friction heat and plasticity flow makes it possible to join the interface of layered dissimilar metals with the minute joining width. The temperature rises are measured at the bottom surface of the layered stainless steel under the conditions of the different keeping times and various indentation depths of the tool. It is shown that joining and non-joining conditions are deeply affected by the temperature distribution and the proposed solid-phase joining method enables the high coefficient joining.
